PAPER BEATER Application led February 25, 1928.y Serial No. 257,042.`

My invention relates to an improvement in paper beaters, and the primary object thereof is to provide a metal covered filler instead ofthe ordinary wood filler, thereby preventing any deterioration or particles of the wood vfiller from entering the stock, which deterioration of the filler is caused by chemical action of the ingredients used in Vpaper stock.

Another objectrofmy invention is Vto pro vide a metal covered filler that will tofa great extent resisty the chemical action of the in gredients used in the stock, thereby prolonging the life of the filler and doing away with the case of frequently changing the wood filler. v i y i `With theabove and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangements of parts, and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention; i

In the accompanying drawings: l Figure v1 is an elevation in partsection. Y Figure 2 is an end view in part section.

Figure 3 is a partial view of the center beater roll head and blade. Y

Figure l is a partial view in section of the center beater roll head.

Referring now in detail to the drawing by means of the numerals: 1

1 refers to the blades of the beater rolls and the blades set in slots 1G cutin heads 14; and 7. The outer ends of the blades are provided with a U shaped slot for the insertion of the rings 13 on the two outer heads which rings are shrunk on the heads. The outer heads are also provided with a flange 20 so that the under side of the blades 1 may rest on this flange and set at a predetermined distance above the heads. The center head 7 is provided with a double flange 18 to hold the blade 1 at a predetermined distance above the head, and the said flanges are in the same horizontal plane as the flanges on the outer heads. The blade 1 is provided with an L shaped slot 15 in the center as indicated by the numeral 15 so that the blade 1 may be removed from the center ring 13, which ring is also shrunk on the head. The heads 7 and 14 are keyed yto the shaft 6, and the head rings 2 are fastened and secured to the outer heads 14 by means of the countersunk screws 4, and the rings extend a predetermined distance above the heads and below the blades 1.` The head rings 2 are alsoprovided with a center 'opening 5 so that they maybe placed over the shaft 6 and against the heads 14. Two se arate Lwood fillers 12 are placed between the heads 7`and'1ll, andthe fillers are notched at the ends so that they set against the heads and on the lianges 1S and 20 of the said heads, and may be designed to come flush with the top of the heads ofthe rings 13.

, My invention consists primarily of a wood filler 11 that extends between the outer heads 14T, and the wood filler is encased in a metal VVcovering 10, and the met-al coveringfis v-rapped entirely around the wood filler and the seams sealed in a water tight manner, I prefer to use copper for the filler covering, but any suitable material may be used that will resist the action of the chemicals used in the making up the paper stock. Then the metal covered filler is assembled it is placed between the blades 1, and a rod 3, with a countersunk head, runs thru one of the rings 2 and through a groove 17 in the wood filler 11, and is threaded into the other rings Q as in dicated by the numerals 18. and by this means the metal covered filler is held in place. The metal covered filler is transversely of wedge shape design, and is faced between the blades 1, which are radially spaced around the heads, and the metal covered filler is designed to make a snug fit against the sides of the blades, and the outer ends are sweated to the rings 2.

IJVhen the separate wood lillers 1f?. are so designed to come flush with the head and below ,the head rings 13, a recess 19 is provided in the metal covered filler so that it may be superimposed over and in direct Contact with the separate wood fillers. Then the separate wood fillers are designed flush with the head rings 13 the recess 19 may be disposed of as Ihn the separate wood fillers and the head rings with allbe in the same horizontal plane.

From the drawings and the description, it will be seen that I have invented a device whereby the wood filler being enclosed by a metal covering,i I have provided a means whereby any of the filler is prevented from entering the stock as mixed in the tank. The metal covered filler may be removed from the beater roll if necessary by means of a blow vention is primarily designed to of the most important steps in the operation of paper making, and particles of wood, in

the Woodiller that have been actedon by the chemical used in the making-of paper, if al lowed to enter the paper stock, under certain conditions would spoil the stock,` and my inprevent the occurrence of this condition.4

What I claim is: l. In a deviceo'fthe class described comfprisinga met-al covered beater roll filler of transverse wedge shape design,Y head rings rigidly andeexteriorly attached to the beater rolifheads adjacent each end of the metal filler, said rings extending a predetermined i distance above the beater roll heads, and a predetermined distance below the beater roll vblades, a rod extending' between the head rings and attached thereto, said -rod extending parts and by thru the metal covered filler and the headings to hold the same in place. f

2. In a device of the class described conip-rising a metal covered roll beater filler, head rings rigidly and exteriorly attached tothe beater roll heads adjacent each end of the metal covered filler, a rod extending between thehead rings and attached thereto, said rod extending thru the metal cov-ered' filler and the headings to hold the same in place.

3. In a device of the Yclass described `co1nprising almetal covered beater roll filler of` transverse wedge shape design and adapted to fit vbetween the blades of a beater'roll, head rings rigidly and exteriorlyattached to the beater roll heads adjacent each end of the metal covered filler and adapted to fit tight' against the exterior ends of the metal covered beater roll filler and at a predetermined distance above the beater roll heads, and a predetermined distance below the beater roll blades, a rod extending vbetween the head rings and attached thereto, said rod extending thru the metal covered filler and the headings to hold same in place.

'In testimony whereof I aHiX my signature.
